Abstract

The utility model relates to an injection chamber used on a piece of metal die casting equipment, in particular to an injection chamber of a horizontal cold-chamber die casting machine, which comprises two injection chambers and a pouring slot; wherein, the injection chambers comprise a first injection chamber and a second injection chamber, the pouring slot is arranged at the upper part of the first injection chamber, and the first and the second injection chambers are fixedly connected with each other by means of a plurality of evenly distributed positioning devices. The injection chamber has the advantages of simple structure, flexible operations, long service life, and much less use costs.

Description

A kind of injection chamber of horizontal cold-chamber die casting machine

Technical field:

The utility model relates to the injection chamber that a kind of metal die-casting equipment is used, especially a kind of injection chamber of horizontal cold-chamber die casting machine.

Background technology:

Injection chamber is the important component part of die casting machine injection device, and its inside is used to store molten metal, and the cylinder that makes the injection punch head that is sealed and matched with its maintenance within it portion finish injection.At present, the injection chamber of horizontal cold-chamber die casting machine is generally monoblock type, because it is worked under hot state and the impact wear of inner injection punch head, the inner surface serious wear that causes the injection chamber rear end lower, thereby make the excesssive gap between itself and the injection punch head face of cylinder, when molten metal is pushed therein, be difficult to set up pressure, thereby cause injection chamber to lose efficacy, must more renew.Will make injection chamber shortening in service life like this, cause very big waste, also increase use cost simultaneously.

The utility model content:

The utility model provides a kind of injection chamber of horizontal cold-chamber die casting machine, and it is simple in structure, flexible operation, and long service life greatly reduces use cost, has solved problems of the prior art.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises injection chamber and pouring slot, described injection chamber comprises first injection chamber and second injection chamber, pouring slot is located at the top of first injection chamber, fixedlys connected by several equally distributed positioners between first injection chamber and second injection chamber.

Described positioner is a bolt, and described bolt is four.

The utility model adopts split type injection chamber, first injection chamber is fixedlyed connected by equally distributed bolt with second injection chamber, when the bottom inner surface when second injection chamber that makes may wear to a certain degree, by regulating bolt, second injection chamber is rotated a certain angle, and the bottom inner surface of second injection chamber that makes changes the new inner surface that did not did not wear and tear into, guarantees the operate as normal of injection chamber, to increase the service life of injection chamber, reduce the use cost of enterprise simultaneously greatly.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that A-A among Fig. 1 is to cutaway view.

Fig. 3 is that B among Fig. 2 is to partial view.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in FIG., the utility model comprises injection chamber and pouring slot 1, described injection chamber comprises first injection chamber 2 and second injection chamber 3, and pouring slot 1 is located at the top of first injection chamber 2, fixedlys connected by several equally distributed positioners between first injection chamber 2 and second injection chamber 3.Described positioner is a bolt 4, and bolt 4 can be four.Described positioner also can be with bolt 4 can be equal to other alternative positioner.

During use, molten metal enters first injection chamber 2 and second injection chamber 3 by pouring slot 1, and finishes injection under the propelling of injection punch head.In injection process, owing to the eccentric reason in the injection punch head horizontal movement, can cause the wearing and tearing of the bottom inner surface of second injection chamber 3, the long excessive gap of appearance between the face of cylinder of the wearing and tearing bottom inner surface that may cause second injection chamber 3 and injection punch head, so that injection chamber lost efficacy, can't work.Therefore, after injection chamber work a period of time, adjust bolt 4, second injection chamber 3 is rotated a certain angle, make the lower surface of second injection chamber, 3 inside become the new surface of not wearing and tearing, fixedly connected by bolt 4 again with nonabradable first injection chamber 2.Owing to locate along the equally distributed bolt 4 of circumference by four between first injection chamber 2 and second injection chamber 3, second injection chamber 3 can rotate and use four times, slow motion when first injection chamber 2 passes through owing to injection punch head, be difficult for it is caused wearing and tearing, so just can increase substantially the service life of injection chamber, reduce use cost simultaneously greatly.

Claims

1, a kind of injection chamber of horizontal cold-chamber die casting machine, comprise injection chamber and pouring slot, it is characterized in that: described injection chamber comprises first injection chamber and second injection chamber, pouring slot is located at the top of first injection chamber, fixedlys connected by several equally distributed positioners between first injection chamber and second injection chamber.

2, the injection chamber of a kind of horizontal cold-chamber die casting machine according to claim 1 is characterized in that: described positioner is a bolt, and described bolt is four.
